Don visiting from South Korea in near prefect position. Can you spot the flaw?

Learning to stabilize the spine is critical if you want to be efficient at the basic gymnastics skills we practice in CrossFit. You need to be tight if you want to be good at pull-ups, push-ups, air squats, handstands and the like. Learning to be stable with and under load is equally difficult and valuable. All the barbell work we do is as good for the midline as it is for the limbs. If we can develop stable and efficient movement patterns we will likely stay injury free and continue to build capacity forever.
